T49HbtFitBase
class description - source file - inheritance tree (.pdf)
This is an abstract class, constructors will not be documented.
Look at the header to check for available constructors.

Some output
void SetHistos(TH3D* numerator, TH3D* denominator)
Set the numerator and denominator

void Bin1ToBin3(TH3D* histo, Int_t bin, Int_t& binx, Int_t& biny, Int_t& binz)
Actually this should be provided by ROOT ... grrrr
return bin number of every axis (binx,biny,binz) if the general bin number (bin) is known
general bin = binX + binY * (nbinX+2) + binZ * ((nbinx+2) * (nbiny+2) ) (+2 acounts for over and underflow!)
TH3D* Ratio()
If normalization was part of the fit we have to scale the ratio histogram for projection etc. ...
void SetCoulombCalculator(TH3D* MeanQinv3dHisto, T49HbtCoulomb* CoulombCalculator, Double_t purity , Double_t momentumres)
Switch coulomb correction on
Double_t Lnfactorial(Double_t arg)
Return the factorial of arg
void doFit()
everything is set up: start minimization !
